Since mid-last season, in most of my games (not every), the home teams have had a huge possession disadvantage although the nominal possession bonuses may be even 15% into the home side's advantage.
Examples. My possession numbers against the same, fairly equally rated team: 44% home, 57% away. Against another club of similar quality: neutral Cup final 50%, away in League 61%. Home against a two whole stars weaker team with 15% bonus for me: 52%.
Have you experienced the same?
Also I've noticed that this hasn't happened when the home manager isn't present. (Which is why I've stopped watching my home games). Coincidence or not?
